Abstract: In order to study morphological response of wheat to different nitrogen sources a field experiment was conducted during the rabi season of 2017-2018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar .The soil of the experimental field is slightly alkaline in reaction, sandy loam in texture, low in organic carbon and nitrogen, medium in available phosphorus and potassium. The experiment was laid out in Randomized Block Design replicated thrice with ten treatments viz. T1 (Control) , T2 (Vermicompost @ 6 t ha-1) , T3 (Azotobacter + Vermicompost @ 6 t ha-1), T4 (30 kg N ha-1 + Vermicompost @ 3 t ha-1), T5 (40 kg N ha-1 + Vermicompost @ 2 t ha-1), T6 (50 kg N ha-1 + Vermicompost @ 1 t ha-1), T7 (30 kg N ha-1 + Azotobacter + Vermicompost @ 3 t ha-1), T8 (40 kg N ha-1 + Azotobacter + Vermicompost @ 2 t ha-1), T9 (50 kg N ha-1 + Azotobacter + Vermicompost @ 1 t ha-1) and T10 (60 kg N ha-1). The results of the experiment indicated that no variations in plant population at 15 DAS and N, P and K status of soil after harvesting of wheat crop was observed due to application of various combinations of nitrogen fertilizer, vermicompost and Azotobacter. Among various treatments of nitrogen fertilizer, vermicompost and Azotobacter T10 was at par with T8 and T9 for plant height at all the stages of crop growth. Treatment T10 at all the stages of crop growth resulted in highest dry matter accumulation. Treatment T10 (100 % RDN) being at par with treatment T9 and T8 required significantly higher number of days to attain physiological maturity than all other treatments. Treatment T10 resulted in highest grain yield which was at par with treatments T8and T9 and significantly higher than all other treatments. Straw yield obtained with treatment T10, was significantly higher than all other treatments except T9. Highest biological yield was recorded with treatment T10 which was at par with treatments T8 and T9.
